How do interactive grids process row changes?

We have a blank interactive grid (image1) that does not assign/insert data as expected. The selected data (image2) will not assign to MED program as expected. It will instead assign to a different program when saved. A PL/SQL Code process is handling our insert via a IF :APEX$ROW_STATUS = 'C' clause. The Associate Type and Program are both select lists items. Any thoughts on why this is happening and how to correct it?
